How To Reset Camshaft Position Sensor, No Start & Without Scanner crankshaft Reset

Last updated on January 1st, 2023 at 06:03 am

If don’t have a functioning camshaft position sensor, your car’s performance will suffer significantly, as it won’t be able to accurately monitor or adjust its valve timing accordingly. This can lead to decreased gas mileage, rough idling, or stalling issues when starting up your car. Today, I will be discussing how to reset the camshaft position sensor.

There are symptoms of a bad camshaft which we discuss in the other article hereand whenever these signs emanate, it could be time to fix some issues within some parts of your car. However, when you have fixed the cause of the camshaft passion sensor problem, you then reset it. But the question is, “is it possible to reset the camshaft position sensor? “Read on to find out. 

So in this article, I will be addressing the following area of camshaft position sensor which are: how to reset camshaft position sensor,  will disconnecting battery reset crankshaft sensor, can i drive with a bad crankshaft position sensor, is it safe to drive with a bad camshaft sensor, tips to follow on how to reset camshaft position sensor, how to reset crankshaft position sensor no start situation,  and finally we will look at how to reset crankshaft position sensor without scanner by yourself.  So with that in mind, let’s get right into them. 

Will disconnecting the battery reset crankshaft sensor

Disconnecting your battery may seem like an extreme measure, but it can help reset any problems with your crankshaft sensor without having to replace or repair anything else.

The reason for this is that when you disconnect the battery from its power source, all stored data will be cleared out completely, including any faulty signals sent by a malfunctioning crank angle sensor (CAS). As such, once everything has been wiped clean and reconnected, it should start working properly once more.

It’s important to note that while disconnecting your vehicle’s battery might solve short-term issues related to CAS malfunctions or errors; long-term fixes may require further investigation into what caused them to begin repairs accordingly.

Additionally, always make sure you have not only disconnected both terminals from their respective sources but also made sure they have securely fastened back up afterward before attempting to restart or drive away again after completing these steps successfully.

Can I drive with a bad crankshaft position sensor?

Driving with a bad crankshaft position sensor can be extremely dangerous and is not suggested.

When this component fails or starts to malfunction, it can cause serious issues with your car’s overall performance and safety.

Is it safe to drive with a bad camshaft sensor?

Yes, it is okay to drive with a bad camshaft sensor though it is not recommended. You should be more concerned about the effect on the engine. It can cause a variety of issues that may affect how well your vehicle runs and even lead to breakdowns while driving. Also, fuel consumption is more likely to increase significantly.

The most common symptom associated with a malfunctioning camshaft sensor is poor fuel economy due to misfires in the cylinders during operation. This means that if you continue driving with this issue unresolved, you could end up spending more money at the pump than necessary.

In addition, faulty sensors can also cause stalling or rough idling when starting up from a stoplight or intersection—which could potentially put you and other drivers in danger if they are not expecting such sudden stops.

Tips on how to reset camshaft position sensor

Most times, when the camshaft position sensor is bad, the option is to replace it. However, in some cases, it can be reset. Depending on  type of vehicle you have and its age, resetting is even possible.

Newer vehicles often include electronic sensors that cannot be adjusted manually like older models, which could be done so easily by hand-held tools such as a multimeter or oscilloscope.

To reset the camshaft position sensor on most vehicles, you will need access to an OBD-II scanner or code reader tool that can read trouble codes from your vehicle’s diagnostic system to diagnose what might be causing problems with its performance, such as misfiring cylinders or poor acceleration due to low voltage readings from its sensors.

Once plugged into your car’s computer port (usually located under the dash), follow the instructions provided by the scan tool manufacturer on how to clear codes stored within the ECU’s memory related to bad Cam Sensor readings. 

After clearing all error codes associated with a faulty cam position sensor, start the engine and let it idle until the temperature gauge reaches its normal operating level.

Then drive around town at moderate speeds, allowing time between stops, so the ECU has enough time to relearn the new parameters it needs to operate correctly again after the replacement of the defective part. Let’s now look at how to reset crankshaft position sensor no start situation below. But What causes no crank, or camshaft no start issues?

What causes no crankshaft position sensor, and no start issue?

The most common cause is an unstable pumping of fuel to the engine, which makes the engine not run well because it is not getting the required fuel supply, and so the engine shuts down. Other possible causes may be a bad or faulty fuel injector or a damaged fuel filter.

Here are the steps  to apply when attempting to reset your crankshaft position sensor when it won’t start:

  1. First off, connect the system scanner to your car’s computer. This will allow you access to its internal systems and help diagnose any issues that may be causing problems with your vehicle’s performance or starting capability.
  2. Once connected, you should fix the car into place by installing brakes on all four wheels and closing both hood latches securely before blocking off steering wheel movement entirely, as well as setting the parking brake firmly in place if applicable for safety reasons.
  3. Next up, select CASE (Crank Angle Sensor Error Code) within the system scanner menu. After selecting this option, input the target RPM value, then hold down the accelerator pedal fully while pressing the Start button until the tachometer needle reaches the specified value. At this point, press the Stop button and completely release the accelerator pedal after that.
  4. Finally, wait a few seconds until the ECU finishes calibrating the CPS, then restart the engine without touching anything else during the procedure; otherwise, calibration may fail, requiring the entire process to be repeated from the beginning.

Following these steps correctly, one should have successfully reset the crankshaft Start problem, allowing them to drive away without further incident. However, if the issue persists despite trying the above method, then more likely something else has wrong, such as a faulty wiring connection or failed part itself, thus needed professional help.

how to reset crankshaft position sensor without scanner

Normally you will need a scanner to clear or reset the crankshaft position sensor, but if you can’t lay your hands on a scanning device, here is how to reset the crankshaft position sensor without a scanner:

  • To reset a crankshaft position sensor without a scanner, accelerate your vehicle to 55 mph while maintaining part throttle for several minutes before decelerating back down to 45 mph without using brakes for one minute.
  • After this, four additional deceleration cycles should be performed where no specific speed needs to be maintained over 25 seconds each time until finally coming back down below 10 mph again without using brakes or other devices such as cruise control during any stage of this process.

Important Notes: Before undergoing this process, ensure that the car is in the park position!

Conclusion

Resetting a camshaft position sensor can help restore the proper operation of your vehicle’s engine if it is an issue with misfiring. If you’re using a scanner, the job will be easier. On the other hand, without a scanner, it requires some technical know-how. Make sure you follow the procedures.

So in this article, we have discussed the question, will disconnecting battery reset crankshaft sensor, is it safe to drive with a bad camshaft sensor? And how to reset crankshaft position sensor no start situation and even resetting  crankshaft position sensor without a scanner. I hope you were able to resolve your car problem.
